Abstract— The effectiveness of latex production is not significant with the rubber land expansion in Indonesia to other rubber-producing countries. Therefore a simple approach to boost productivity is necessary. Fertilization, a simple procedure that is vital in enhancing latex production, has the potential to raise the rubber industry's pollution impact. As a result, the injection and infusion approach is being used as a green technological endeavor to fertilize mineral nutrients to boost latex production in rubber trees. The research was conducted from April to August 2015 in PT. Perkebunan Nusantara VIII at Bagjanagara and Bunisari Lendra Plantation,West Java, Indonesia. The nutrient solution in various concentrations was applied by infusion or injection at the rubber trunk. The nutrient solution contained N, P, K, Ca, Mg, S, Fe, B, Cu, Zn, Mn, and Mo. The results showed that on lower 20 years old rubber increase of latex and dry rubber yield significantly in the trees that were given nutrient solution by injection without dilution of nutrient solution, and by infusion with the dilution of nutrient solution at 20 mL.L-1 and no applied nutrient solution. The heights of the infusion on the trunk at 50 cm from the ground with the dilution of nutrient solution at 10 mL.L-1 give the effect on the highest latex and dry rubber yield. Concentrate of 20 mL.L-1 nutrient solution in infusion application on the trunk of tapping panel dryness gives the effect on higher latex yield than normal rubber tree of the upper 20 years old.
